Web7 feb. 2024 · For a person with hypermetropia, the near point has moved to 1.5 m. Calculate the focal length of the correction lens in order to make his eyes normal. Solution: Given that, d = 1.5 m; D = 25 cm = 0.25 m (For a normal eye). The focal length of the correction lens is, Samacheer Kalvi 10th Science Optics Textual Evaluation Web30 mrt. 2024 · Since the hypermetropia. The type of lens used to correct hypermetropia is a convex lens. Near point = 1 m means that person can see object placed at 25 cm clearly if the image is formed at 1 m. To find the power of the lens, we need to find its focal length. So taking, Since the object is in front of the eye, object distance will be negative. hour registration template
